SIMPLE tech. Making a drawing on metal without expensive materials

It's really easier than it seems. I make drawings on metal at home. The design on the knife is made using electrochemical metal etching and engraving. This is a simple technology accessible to everyone. SIMPLE tech. In the video I show the step-by-step process accompanied by pleasant music. I wish you pleasant viewing.
